UNITED STATES PATENT OFFICE.

FRANK L. IRWIN AND JOHN E. TESSEYIVIAN, OF COLUMBUS, OHIO, ASSIGNORS TOTHE RALSTON STEEL CAR COMPANY, OF COLUMBUS, OHIO, A CORPORATION OF OHIO.

RAILWAY-CAR.

T '0 all whom it may concern:

Be it known that we, FRANK L. IRWIN and J 01m E. TESSEYMAN, citizens ofthe United States, residing at Columbus, in the county of Franklin andState of Ohio, have invented certain new and useful Improvements inRailway-Cars, of which the following is a specification.

This invention relates to railway cars and more particularly to dumpingcars, the object of the invention being to provide a car having hingedbottom sections together with means for effectively controlling themovement of said sections and for locking said sections in their closedpositions without undue strain upon the locking parts.

Further objects and advantages of the invention will be set forth in thedetailed description which now follows.

In the accompanying drawings, Figure 1 is a view partially inlongitudinal section and partially in side elevation of a dumping carconstructed in accordance with the invention, Fig. 2 is a partial planview thereof with one of the hinged bottom sections broken away, Fig. 3is an end elevation of said car, and, Fig. 4 is a transverse verticalsection of a portion of said car with some of the parts omitted.

Like numerals designate corresponding parts in all of the figures of thedrawing.

Referring to the drawings, the numeral 5 designates the car truck, 6 theside walls and 7 the end walls of the car body. The floor of the carcomprises a plurality of transverse sills, said sills comprising channelbeams 8 and horizontal floor plates 9. A longitudinally extending truss10 has secured thereto at intervals, brackets 11, these brackets beinglocated at the center line of the car. Hingedly connected to thesebrackets are swinging floor sections 12 and 13 and it is in the meansfor controlling the movement of these floor sections that the presentinvention more particularly resides.

Extending transversely of the car at intervals, are webs 14 and 14Bearing plates 15 are secured to the faces of these webs and togetherwith hearing brackets 16, provide supports for longitudinally extendingshafts 17 and 18. Mounted to swing loosely upon the outer ends of theseshafts are levers 19 and 20, these levers carrying pawls 21 and 22,which engage ratchet wheels 23 and 24.

Specification of Letters Patent.

Application filed June 6, 1910.

Patented Nov. 29, 1910.

Serial No. 565,170.

To prevent retrograde movement of the shafts during the time that thedoors are being moved to their closed positions, pawls 25 and 26 arepivoted to the end wall of the car and engage ratchet wheels 27, onlyone of which is shown.

The swinging sections 12 have their side and outer edges 28 and 29downturned for the purpose of strengthening these sections and renderingthem rigid. Brackets 30 carried by these swinging sections, haveantifriction rollers 31 pivotally mounted thereon, these rollers bearingupon the upper side of levers 32. The outer ends of these levers areslotted at 33 for the reception of a pivot 34 which pivotally andslidably connects said lever to bearing members 35 carried by theadjacent transverse beams. The lever 32 has its upper face curved asshown and is provided with a hook extension 36. A slot 37 is formed inthe inner end of each of the levers 32 for the reception of a pin 39which pivotally and slidably connects the lever to a link 40. Theopposite end of this link is pivotally connected at 41 to a crank 42which is fast upon the shaft 17, it being understood that this structureis duplicated at each side of each of the door sections. It is to benoted that the link 40 is provided with a shoulder 43 (see Fig. 4).

The operation of the device is as follows: When it is desired to lowerthe door sections to thereby discharge the contents of the car, thepawls 25 and 26 are moved out of engagement with their ratchet wheels 27and 28 and movement is imparted to the shafts 17 and 18 by means of thelevers 19 and 20 and the pawl and ratchet wheels 21, 22, 23, and 24.

Referring to Fig. 4 particularly, the direction of movement of the shaft17 will be in the direction of the arrow. This will swing the crank 42first upwardly and then over toward the left, the pivot 39 sliding inthe slot 37 and the lever 32 by reason of its slotted engagement withthe pivot 34 sliding bodily toward the left in Fig. 4 until the crankpasses over the center, whereupon the door sections, the lever 32, thelink 40 and the crank 42 will drop to the position illustrated in dottedlines in Fig. 4 and the contents of the car will be discharged. It isapparent that since the movements of the levers 19 and 20 are entirelyindependent of each other, the contents of one side of the car may bedischarged independently of the other side thereof.

\Vhen it is desired to again close the doors, the pawls and 26 are movedinto engagement with the ratchet wheels 27 to prevent retrogrademovement of the shafts and the shafts are rotated to return the parts tothe position illustrated in full lines in Fig. 4- and since theoperation of all of the door controlling mechanisms is the same, theoperation will be described with relation to the structure shown in fulllines in Fig. l. It will be noted thatwhen the parts are dropped to thedotted line positions shown in Fig. 4:, the roller 31 lies in the hook236 and the door is thereby supported in its lowermost position.

Then the shaft 17 is started to rotate toward the right in Fig. at, toreturn the parts to the full line position, the link etO follows thecrank 42 until the shoulder as abuts against the shaft; continuedrotation of the crank will then rock the link 40 upon the fulcrumprovided by the shaft 17 and shoulder as, the movement of the lower endof the link 40 causing the pivot tl to travel to the left-hand end ofthe slot 3'? and causing the lever 32 as a whole, to travel upwardly andoutwardly to its limit of movement toward the left. Continued movementof the crank will ultimately bring the parts to the full line positionshown in Fig. 41-, at which time the pivots 39 and 11 are in alinementwith each other and with the shaft 17 and the crank 12 is on its deadcenter. The doors are then positively located in their closed positionsand the weight of the doors tends to hold the shafts 17 and 18 againstrotation, rather than to tend to rotate said shafts. These parts form infact a powerful toggle mechanism which provides great leverage to aidthe operator in closing the doors and which positively locks the doorsagainst opening after they have reached their closed positions, as willbe readily understood.

From the foregoing description, it will be seen that simple andetiicient means are herein provided for accomplishing the objects of theinvention, but while the elements xhown and described are well adaptedto serve the purposes for which they are in tended, it is to beunderstood that the invention is not limited to the precise constructionset forth, but includes within its purview such changes as may be madewithin the scope of the appended claims.

\Yhat we claim, is:

1. The combination with a car body, of a plurality of floor sectionshingedly connected thereto, a rotative shaft arranged beneath said floorsections, pivotally and slidably mounted levers located beneath saidfloor sections and upon which said sections bear, crank arms on theshaft, and links connecting said arms with the levers, said links beingadapted to bear against the shaft when the doors are closed.

2. T he combination with a car body, of a plurality of floor sectionshingedly connected. thereto, a rotative shaft arranged beneath saidfloor sections, pivotally and slidably mounted levers located beneathsaid floor sections and upon. which said sections bear, cranks on theshaft, links connecting the shaftv and levers, anti-friction memberscarried by the floor sections and bearing upon the levers, and a hookextension at the inner end of each of said levers, with which theanti-friction member engages when the door is in its lowermost limit ofmovement.

3. The combination with a car body, of a plurality of floor sectionshingedly connected thereto, a rotative shaft arranged beneath said floorsections, a pivotally and slidably mounted lever located beneath saidfloor sections and upon which said sections bear, and toggle mechanismconnecting said levers and said shaft, said toggle mechanism comprisinga crank fast upon the shaft, a link one end. of which is pivotallyconnected to said c ank and the other end of which is slidably engagedwith said lever.

4. The combination with a car body, of a plurality of floor sectionshingedly connected thereto, a rotative shaft arranged beneath said floorsections, pivotally and slidably mounted levers located beneath saidfloor sections and upon which said sections bear, and toggle mechanismconnecting said levers and said shaft, said toggle mechanism comprisinga lever having a shoulder intermediate its ends which abuts against andfulcrums upon said shaft.

5. The combination with a car body, of a drop door, a lever pivotallyconnected with the underframe of said car at its outer end and forming asupport for said door, the inner end of said lever having a slot and amember engaging said slot to support the inner end of the lever andthereby support the door in closed posit-ion.
